SPECIFICATION forming part of Letters Patent No. 618,482, dated January31,' 1899.

Application filed February 1, 1898. Serial No. 668,727- (No model.)

To @ZZ whom t nto/y con/cern:

Be it known that I, THOMAS ROBERTSON, manufacturer, of the city ofToronto, in the county of York, in the Province of Ontario, Canada, haveinvented certain new and useful Improvements in Oonfectionery-Ornamenting Machines, of which the following is a specification.

My invention relates to improvements in confectionery ornamentingmachines; and the object of the invention is to design a machine wherebychocolates, bonbons, and biscuits and other fancy confectionery may bedecorated expeditiously; and it consists, essentially, of a reservoir tocontain the decorating mixture, suitably supported and having flexibletubes leading from metallic tubes extending from the bottom of thereservoir, such flexible tubes being connected at the bottom to nipplessuitably supported and driven, so as to have any desired motion over thearticles to be decorated, which are preferably fed in under the nipples,from which the decorating mixture is caused to exude, by endless bandssupported on a suitable table, the parts being otherwise constructed andarl ranged in detail as hereinafter more particularly explained.

Figure 1 is a perspective view of the machine complete. Fig. 2 is aperspective vieW from the rear of the machine. Fig. 3 is a verticalsection through the machine. Fig. 4 is an enlarged plan view of thebands, showing one form of decorating, the nipples being shown in dottedlines. Fig. 5 is a detail of the adjustable crank-Wheel.

In the drawings like letters and numerals of reference indicatecorresponding parts in each ligure.

A is the main frame of the machine, which is rectangular in form.

B is the table, which is provided With side bars B B and central portionB?, aflixed thereto. The side bars are provided at one end with endjournal-brackets l), through which and the supporting journal-brackets Oextends the cross-shaft b. The opposite ends of the side bars B havesecured to them the depending hangers D, having slots d `at the lowerend. Through the slots extend the clamping-screws cl', which may beloosened or tightened, so as to rigidly hold the table at this end whenit has been adjusted to the desired height.

In order to provide for nicety of adjustment, I provide thescrew-spindle E, which extends through the end bar of the frame andabuts a depending projection b2 on the free end of the table B. Iprovide an adjustment at this end of the table for the purpose ofbringing the table and bands F thereon nearer to or farther from thenipples-G in order to accommodate different thicknesses of confections.o The bauds F are endless bands and extend over the end grooved pulleysF and F2, suitably journaled in bearings attached to the table. Thebands F extend over the top of the table, and in Order to place theconfections in position I provide the guides I-I I-I, located to theoutside of each band and provided with slots hand set-screws h. By thismeans I insure' the confections being placed straight upon the band.

The nipples G, hereinbefore alluded to, are located in holes on theT-shaped end of the heating-tube I, Which is provided with an open cageI' at the bottom end and a burner I2 at the lower end of the cage. AT-shaped tubular joint I3 is provided, into Which leads a tube I4, inwhich the gas is supplied to the burner. The lower end of the jointI3 isprovided With a socket t', Which is supported on the top of theset-screw t2, extending through the cross-bar I5. The heat passing upthrough the tube I and out through the open ends of the T-shaped upperend/L' serves to keep freely soluble the exuding chocolate, sugar, orother mixture.

J is a reservoir containing the mixture designed to ornament theconfection. The reservoir J is surrounded by a Water-jacket J in whichhot Water is held. The reservoir J is pivotally supported by trunnions 2in bearing-joints j at the top of the arms J 2, which extend throughslots b3 in the table and are secured on the cross-bars of the mainframe.

The reservoir J is provided at the lower end with downwardly-extendingtubes j j,leading from the bottom thereof, Which tubes are connected tothe nipples G G by the flexible tubes j?, made of rubber or othersuitable llexible material, in order to permit of a limited horizontalmovement.

horizontal movement, which in the present IOO In order to impart thisinstance is in all directions, I provide a coupling K, which isconnected by a rod k to a crank-wheel L, secured on the end of acrossspindle Z, supported in suitable bearings on the end of themachine, and a rod m to a crank wheel M, secu red to a longitudinalshaft M, supported in suitable bearings at the rear of the machine. Boththe crankwheels are preferably constructed as shown in Fig. 5, in whichit will be noticed that the eyeshaped end of the operating-rod isconnected to a pin n on the side of the block N,whieh is supported in asuitable guideway N', ex-

tending` diametrically across the wheel. Setscrews N2 are provided,which by being adjusted up or down will impart the desired amount ofthrow through the rods to the heating-tube I, and consequently to thenipples G. The result of this throwis exhibited in one form ofornamentation 3 shown on the confection l shown in Fig. 4. The form ofthe ornamentation of course greatly depends upon the rapidity at whichthe bands cause the confection to move underneath the nipples G.

It is well known that in chocolate ornamentation the mixture must bekept warm, and for this reason I provide the water-jacket hereinbeforedescribed.

I shall now describe the means by which the nipples are given thedesired movement and the speed thereof changed as may be desired. On theshaft M', I provide a cone-pulley M2 and a beveled pinion M3,whichmeshes with the beveled pinion M4 on the end of the cross-spindle Z.This bevel-pinion M3 is made in this instance double the size of thebeveled pinionM4 to impart the desired ornamentation; but these beveledpinions maybe of any desired size in relation to each other. Thecone-pulley M2 is connected to the cone-pulley O, supported on thespindle o by a belt O, which passes through the shifting-jaws p, formingpart of the bar P, attached to the sleeve P. The sleeve P' is providedwith an arm P2, through the end of which extends a screw-spindle P3,provided with an end-turning handle p'. As the end of the screw-spindleP3 rotates freely in the bearings, it will. be seen that the adjustmentof the belt on the cone-pulleys is easily eifected. Such adjustmenteffectually provides for increasing or decreasing the rapidity ofmovement of the nipples G, as required by the degree of solubility ofthe mixture passing through them.

The endless bands F are driven at the hinged end of the table throughthe pulleys secured on the cross-shaft b. On the outer end of thecross-shaft (see Fig. 2) is secured a wormby precisely the same style ofmechanism referred to for shifting the belt upon the conepulleys M2 andO.

By adjusting the belt Q2 upon the conepul leys Q and Q3 of course thespeed at which the bands upon which the confections are placed aredriven is also varied, according to the rapidity with which the mixturemay be caused to exude from the nipples G in dii'l'er ent classes ofornamentation.

Upon the top ofthe reservoir I provide a suitable cap R, having asafety-valve o' and a pressure-gage r of any usual construction. Thecenter of the top of the cap is connected by the pins R, extendingthrough the boss R'e 'to the spindle S, such set-screws extending into agroove s in the spindle, thereby permitting of the free rotation of thespindle S and yet forming a means for lifting the cap. The spindle S isa screw-spindle for the major portion of its length and has secured toit a hand-wheel T. The upper end'of the serewspindle S extends through acrossbar U, pivotally swung in the hanging frame U', which infitself hasthe side bars of the frame pivotally connected to lugs u, attached to atop sup porting-plate u', suitably connected to the ceiling.. The frameU may also be provided with a suitable counterbalancing-weightsufficient to counterbalance the weight ofthe cap R. Connected to thetop of the reservoir is a tube V, through which the pressure is exertedupon the top of the mixture. By turning the hand-wheel T so as to raisethe spindle in the cross-barU the lid may be raised from the top of thereservoir and swung out into any desired position, any suitablecounterbalancing-Weight serving to retain it in such position. By thisarrangement I am enabled to get at the contents of the reservoir or tofill it, as the case may be. It will also be noticed that the reservoiris swung on trunnions 2 at right angles to the cross-bar support for thecap, thus enabling me to secure an accurate fit of the lid upon the topedge of the reservoir. The lid would necessarily fit upon the top edgetight and be held thereon by means of the screw-spindle S, the cross-barU, and its accompanying parts.

Although I show two nipples G and two bands for conveying theconfections or other articles to be ornamented underneath the nipples G,it will of course be understood that I might use one nipple and one bandor more than two nipples and bands,which would have the desired motionimparted to them.
